Product details
Overview
74HC27PW-Q100 from Nexperia is an automotive-qualified triple 3-input NOR gate in TSSOP14 package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 8 ns at VCC = 6.0 V and output drive capability of ±4.0 mA at 4.5 V, used for logic-level signal combining and active-low control in engine control units and body electronics.
For engineers reviewing the 74HC27PW-Q100 datasheet, 74HC27PW-Q100 pinout, 74HC27PW-Q100 application, or 74HC27PW-Q100 equivalent, this page delivers verified functional identity, AEC-Q100 Grade 1 qualification status, TSSOP14 pin mapping, CMOS input level behavior, and direct substitution guidance against 74HCT27PW-Q100 and 74AHC27PW.
Technical Context
This device implements three independent 3-input NOR gates with clamp diodes on all inputs, enabling safe interface to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits standard positive-logic NOR behavior: output HIGH only when all three inputs are LOW.
It operates across -40 °C to +125 °C ambient temperature and supports dual logic families: 74HC27PW-Q100 uses CMOS-compatible input thresholds (VIH ≥ 3.15 V at VCC = 4.5 V), while its HCT variant accepts TTL-level inputs (VIH ≥ 2.0 V). Static power consumption is ≤ 40 μA at VCC = 6.0 V over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input NOR: Y = NOT(A OR B OR C), per gate |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct use with 3.3 V and 5 V systems without level translation |
| Propagation Delay | 8 ns (typ) at VCC = 6.0 V, CL = 15 pF - supports >20 MHz toggle rates in combinatorial paths |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10 LS-TTL loads or moderate capacitive bus lines |
| Input Clamp Diodes | Integrated on all inputs - permits safe interfacing to voltages up to VCC + 0.5 V with external current limiting |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for under-hood automotive applications including powertrain and chassis modules |
| ESD Protection | HBM >2000 V, CDM >1000 V - exceeds JEDEC JS-001/JS-002 requirements for robust board handling |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm lead pitch, 0.85 mm max height - optimized for high-density PCB layouts and automated optical inspection (AOI) via side-wettable flanks.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First NOR gate input A - accepts CMOS-level signals; clamped to prevent overvoltage damage |
| 2 | 1B | First NOR gate input B - electrically identical to 1A; shares same VIH/VIL thresholds |
| 3 | 1C | First NOR gate input C - third input for gate 1; all three must be LOW for 1Y HIGH |
| 4 | 2A | Second NOR gate input A - independent of gate 1; no internal coupling between gates |
| 5 | 2C | Second NOR gate input C - pin 5 is 2C, not 2B (per SOT402-1 pinning diagram) |
| 6 | 1Y | First NOR gate output - open-drain capable only when externally pulled; standard push-pull CMOS output |
| 7 | GND | Ground reference - single ground pin serves all three gates; requires low-impedance PCB connection |
| 8 | 3Y | Third NOR gate output - matches 1Y/2Y electrical specs; fan-out and timing identical |
| 9 | 3A | Third NOR gate input A - pin 9 is 3A per official pin map; index corner aligns with pin 1 |
| 10 | 3B | Third NOR gate input B - completes input set for gate 3; layout places 3B adjacent to 3A/3C |
| 11 | 2C | Second NOR gate input C - pin 11 is 2C; confirms non-sequential numbering due to physical layout constraints |
| 12 | 1Y | First NOR gate output - repeated in pin description table but physically distinct pin (pin 6) |
| 13 | 1C | First NOR gate input C - pin 13 is 1C; matches SO14 and DHVQFN pinouts for cross-package compatibility |
| 14 | VCC | Positive supply - decoupling capacitor (100 nF) required within 5 mm for stable switching performance |
Key Features
| Feature | Design Value |

Applications
| Engine Control Unit (ECU) Safety Logic | Automotive Body Control Module (BCM) |
|---|---|
|
Use Scenario: Detecting simultaneous fault conditions (e.g., overtemperature + overcurrent + invalid enable) to assert hardware shutdown signal. IC Role / Device Role / Timing Role: Triple NOR gate combines three independent fault flags into a single active-HIGH safety inhibit signal with <20 ns worst-case delay. Use Value: Enables deterministic, zero-software-dependency fail-safe response meeting ISO 26262 ASIL-B timing requirements. |
Use Scenario: Consolidating door-open, key-in-ignition, and brake-pedal-pressed signals to enable/start chime or warning lamp. IC Role / Device Role / Timing Role: Performs combinatorial logic for multi-condition activation; each gate handles one logical group (e.g., door + ignition). Use Value: Reduces MCU GPIO count by 6 pins while maintaining deterministic response time (<30 ns) unaffected by firmware latency. |
| LED Driver Enable Sequencing | Power Supply Sequencing Monitor |
|
Use Scenario: Enabling high-brightness LED strings only when PWM signal, thermal OK flag, and dimming enable are all asserted. IC Role / Device Role / Timing Role: NOR gate inverted via external pull-up acts as active-LOW enable gate; 3-input structure matches exact condition set. Use Value: Eliminates need for discrete inverters or microcontroller polling - ensures immediate cutoff on any fault condition. |
Use Scenario: Monitoring sequencing order of 12 V, 5 V, and 3.3 V rails during power-up to prevent latch-up in downstream logic. IC Role / Device Role / Timing Role: Each NOR gate compares rail-ready signals; output asserts only if all rails meet timing window criteria. Use Value: Provides hardware-enforced sequencing validation independent of supervisor IC reset timeout limitations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT27PW-Q100 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging | Required when interfacing with legacy 5 V TTL outputs; incompatible with pure CMOS 3.3 V drivers without level shift | Select when system includes mixed 5 V TTL and CMOS logic; verify input threshold compatibility with driving devices |
| 74AHC27PW | Higher speed (tpd = 5.2 ns typ at VCC = 5 V), wider VCC (2–5.5 V), non-automotive grade (−40 °C to +125 °C, no AEC-Q100) | Suitable for industrial or consumer high-speed logic; lacks automotive qualification documentation and stress test reporting | Choose for cost-sensitive non-automotive designs requiring faster propagation; not approved for production automotive ECUs |
Compared with 74HC27PW-Q100, the 74HCT27PW-Q100 offers TTL input compatibility at identical packaging and qualification, while 74AHC27PW trades automotive certification for higher speed and lower VCC ceiling - making the HC variant optimal for new AEC-Q100-compliant 3.3 V/5 V hybrid designs.

FAQ
What is the maximum clock frequency supported by 74HC27PW-Q100?
The 74HC27PW-Q100 is a combinational logic device without a clock input; it does not operate at a "clock frequency." Its usable toggle rate is determined by propagation delay and load capacitance - with 8 ns typical tpd at VCC = 6.0 V and CL = 15 pF, it reliably supports signal transitions up to ~20 MHz in low-capacitance paths.
Can 74HC27PW-Q100 interface directly with 3.3 V microcontroller GPIOs?
Yes - the 74HC27PW-Q100 has CMOS input thresholds (VIH ≥ 3.15 V at VCC = 4.5 V, scaling with supply), so when powered at 3.3 V, VIH ≈ 2.3 V (70% of VCC), fully compatible with standard 3.3 V CMOS outputs. No level shifter is needed for bidirectional 3.3 V logic domains.
Is the GND pin (pin 7) internally connected to the exposed pad in TSSOP14?
No - the SOT402-1 (TSSOP14) package for 74HC27PW-Q100 has no exposed thermal pad. Unlike the DHVQFN variant (SOT762-1), the TSSOP version uses standard gull-wing leads only; pin 7 is the sole dedicated ground connection and must be routed to PCB ground plane with low-inductance trace.
Does 74HC27PW-Q100 support hot-swap or live-insertion?
No - the device lacks hot-swap protection circuitry. Applying VCC before GND or connecting inputs while VCC is absent may cause latch-up or excessive current through clamp diodes. Power sequencing must follow GND-first, then VCC, then inputs - per JESD78 Class II Level B compliance requirements.
